Jury Trial Case Update: Morris Anthony Greenberg Receives Second-Degree Murder Conviction in
DIAMOND SPRINGS, CA — “On March 4, 2026, an El Dorado County jury returned a guilty verdict against Morris Anthony Greenberg, 54, of Diamond Springs, for second-degree murder. The jury also found true that he personally used and discharged a firearm, causing great bodily injury or death.
This case stems from a July 20, 2008 incident in which Greenberg shot and killed Anthony Dumont.
At the time, Greenberg and his wife, Barrie, were separated and going through a divorce. Dumont had recently begun dating Barrie. On the day of the incident, Barrie, Mr. Dumont, and two friends were at the Greenberg’s former residence to move property.
Greenberg arrived at the property and became upset that they were there, yelling at everyone to leave. Dumont, who had been working on removing a horse corral, immediately stopped what he was doing and went to sit in a truck to leave. He did not engage with Greenberg. The two friends also began getting into the truck to leave.
Meanwhile, Barrie and Greenberg continued to argue. During this time, Barrie asked one of the friends to take the Greenberg’s young daughter inside the home to avoid hearing the argument, and they did so. Mr. Dumont remained seated in the truck.
Greenberg then walked to his car, retrieved a firearm, returned to the truck, and shot and killed Dumont.
After the shooting, Greenberg shot himself but survived his injuries.
This case was originally tried in December 2011, resulting in a conviction on January 9, 2012.
Greenberg filed an appeal, which was denied on February 4, 2015. A subsequent habeas petition filed in state court was denied on April 3, 2019. A later federal habeas petition was granted, overturning the conviction and returning the case to El Dorado County for a new trial.
The El Dorado County District Attorney’s Office extends its gratitude to the current and retired El Dorado County Sheriff’s Deputies—many of whom traveled from out of state—as well as the civilian witnesses whose commitment made it possible to secure justice for Anthony Dumont more than 17 years after his murder.
Sentencing is scheduled for April 9, 2026, at 1:30 p.m. in Department 1 of the El Dorado County Superior Court before Judge David Rosenberg.”
